If the total length of the display link cables is 50 to 100 m, connect *SEL5
to a potential of 0 V. This total length should include all display interface
cables. If the total length exceeds 50 m, the Power Mate cannot be made
detachable.
NOTE
The 0–V signals on pins 2, 4, 6, 8, 12, 14, 16, and 18 of JN1
are connected internally on the printed circuit board.
Therefore, connection to any 0–V pin is allowed.
